The Berkshire Museum agreed to pay its former executive director $92,000 to leave his post last June, a month after the institution sold a dozen of its most valuable works.

When Van Shields abruptly left the museum June 26, both he and his employer declined to speak about the financial terms of his departure, which came nearly one year after he trumpeted a “New Vision” for the 105-year-old institution that hinged on selling prized works from its collection.
